Abstract: An electric turbomachine for use with an internal combustion engine, turbocharger or a fuel cell e-compressor, said electric turbomachine comprising: a compressor (20) that is arranged to compress fluid within a turbo compressor when it is rotationally driven about a rotational axis (R) by a shaft, said shaft being rotational supported by a drive-end bearing (65) and a non-drive-end bearing (85), and a high-speed electrical machine located within a housing (50) that is arranged to rotationally drive the shaft about the rotational axis (R); said housing comprising a drive-end wall (60) that the shafts extends through to rotationally drive the compressor, a non-drive- end wall (80) at the opposing end of the electric turbomachine to the compressor, and a side wall (55) that extends between the drive-end wall and the non-drive-end wall, and wherein the electric turbomachine comprises a cooling system (330), for receiving a flow of a coolant fluid to cool the electric turbomachine, that is integrated within the h

Abstract: A turbogenerator power electronics system for use with a turbogenerator is described, wherein the turbogenerator power electronics system comprises a plurality of power electronics subsystems connected in parallel, each power electronics subsystem comprising an inverter. In such a way, a modular, reconfigurable power electronics system with increased ability to operate during a fault is provided.

Abstract: In at least one embodiment, an apparatus for detecting a phase sequence in a vehicle is provided. The apparatus includes a control module for being operatively coupled to a power grid for receiving an incoming power signal therefrom, the incoming power signal providing a first voltage and a second voltage in a vehicle. The control module is configured to determine a phase difference between the first voltage and the second voltage and to determine a signal frequency of the incoming signal to determine a country type for the power grid. The control module is further configured to control a number of switching devices to generate an output voltage signal based on the phase difference and the signal frequency to charge at least one battery on the vehicle.
